Steel fiber is ideal for concrete reinforcement. Evenly in concrete mixed with steel fiber proportion, has become a new engineering material. Steel fiber reinforced concrete in the tensile strength, impact resistance, crack resistance, shear, anti-wear, anti-fatigue, anti-freeze-thaw performance has greatly improved compared with ordinary concrete. Are widely used in various types of concrete work.
At the same intensity can reduce the thickness of concrete, save 20% -30% of concrete volume.
Due to the high tensile strength to get up early and extending the shorter distance, shorten the construction period can be 25%. Especially suitable for fast-watering Huning's request to extend a larger map projects, such as roads, ports, airports, bridges, tunnels and so on.
As the steel fiber reinforced concrete excellent durability, can extend the service life of structures, reduce maintenance costs, significant economic benefits
